The present invention relates to an output relay printed circuit board of a robot and a PLC, and more specifically, to convert a DC voltage output from the robot into a relay contact or an output from a PLC output card. It is a relay printed circuit board that converts DC voltage or AC voltage into relay contacts. On the other hand, it can be used for various types of outputs in general, or can be divided into two chapters. The relay printed circuit board currently used is to change only the PLC output to the relay contact point, and there is a need to use each printed circuit board according to the polarity of the DC voltage. In addition, the output relay printed circuit board of the robot converts only the robot output to the relay contact point, and there is a need to use each printed circuit board according to the polarity of the DC voltage.

As described above, the conventional relay printed circuit board cannot be used for various types of output stages without considering versatility. Therefore, a separate relay printed circuit board corresponding to each of the output voltages and the type of the voltage is required. In addition, since the conventional products are configured separately, such as 16 points, 32 points, a lot of inconvenience in common use.

Therefore, the present invention has been devised to solve the above-mentioned conventional problems, and an object of the present invention is to configure the output of the robot and the PLC (PLC) can be converted to a relay contact in one printed circuit board, It is to provide robot and PLC output relay printed circuit board so that both robot and PLC can be used in common and users can easily change the polarity of DC voltage.

The user can use a single printed circuit board without a separate printed circuit board for the robot and the PLC.

On the other hand, when the output of the robot or the PLC (PLC) is a DC voltage, it is possible to simply miss the polarity of the DC voltage using the common line switching terminal (3). For example, if the output voltage is NPN, short the (+) and (COM) terminals, and in the case of PNP, short the (COM) and (-) terminals to change the polarity of the DC voltage. have. AC voltage relays can be used for printed circuit boards of the present invention.

On the other hand, it is a technical problem that the upper substrate 11 and the lower substrate 12 can be separated and used as the substrate separation hole 7 according to the number of contacts of the relay to be used.
